AAXLE-'BOX FOR CARRlAGES.

SPECIFICATION forming part of Letters Patent No. 389,963, dated September 25, 1888.

(No model.)

To @ZZ whom it may concern.-

Be it known that I, MICHEL GUIET, of the firm of Million, Guiet & Cie., at Paris, (Seine.) in the Republic of France, have invented Improvements in Axle-Boxes for Carriages, of which the following is a specification'.

This invention relates to an improved lubricator, consisting of a metal grease-box so arranged as to secure an effectual and economical lubrication of long duration. This lubricator can be employed with ordinary axle or other grease and presents the following advantages.

First. The suppression of overheating of the axles, and consequently of binding action.

Second. Reducing to its minimum the wear and tear of the axlejournals, washers, nuts, and boxes.

Third. In patent axles for oil or grease the oil-reservoir is dispensed with, and consequently the false bearing which causes the fracture ofthe axles. The box bearing on the axle close to the collar or washer, the section of the latter is increased by the difference of diameter existing between the boss and the barrel. The axle is thus strengthened.

Fourth. For carriages this lubricator has this otherad vantage, that the grease-chambers, of an car shape,fit into the nave without projecting above it and without weakening it. The neat appearance of the wheel is not found to be destroyed.

Fifth. Avoiding the leakage which is produced in ordinary oil or grease boxes, and thereby preventing waste.

Sixth. Owing to defects in casting, there is often a leakage ofoil in the interior of the nave, which spoils the wheel by percolating to the spokes. the use ofthe improved box herein described.

Seventh. The lubricating can be performed without taking off the wheels-a point ofgreat importance in the case of heavy vehicles with large and pondcrous wheels.

Eighth. This box is applicable to all kinds of axles where oil or grease is employed, it only7 being necessary to modify the proportions according to the different needs.

This inconvenience is obviated byl Ninth. No special workmanship or tools are required for fitting the box into the wheels, it being within the capacity of every wheelwright.

Tenth. These boxes do not entail any modication of the axles; and in particular, when combined with patent axles lubricated with oil, they constitute a most perfect system of lubrication.

In order that the said invention may be fully understood, I shall now proceed more particularly to describe the same, and for that purpose shall refer to the several figures on the annexed sheets of drawings, the same letters of reference indicating corresponding parts in both figures.

Figure l is a longitudinal section along the axis of the axle orjournal, and Fig. 2 is a front view ofthe journal-box.

The box, as shown in Figs. l and 2, has two ears, A, inside of which is a reservoir, B, for holding the oil. At the end of the reservoir for closing it is a stopper, C, having on its inner side a spring, p, exerting a pressure on a piston or washer, P, which operates on the surface ofthe lubricant, and causes it to flow out through the channel D, to which feed the oilgrooves E, which can be either straight or helicoidal in shape.

I claim as my invention 1. An axle-box having one or more 1ubri catingehambers, and channels D, each combined wit-h a free piston in the said chamber, a spring to act on the piston, and astopper to close the chamber and confine the spring, substantially' as described.

2. An axle-box having one or more chambers, B, channels D, and grooves E, in com bination with a free piston in the chamber, a spring to act upon the piston, and a stopper to close the chamber and confine the spring.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses..
